3M Marine 69457 Sanding SuppliesCloth Belt 777F protects against heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys with a grinding aid that lowers running temperatures, and the abrasive is resin-bonded to the backing for durability under high heat and pressure. This belt is recommended for dimensioning parts, deburring, blending, and finishing castings and forgings made of stainless steel or other exotic metal alloys. Ceramic abrasives are designed to cut quickly and withstand high heat and stress, making them ideal for moderate to heavy stock removal. The Cloth Belt 777F's ceramic/aluminum oxide blend outperforms aluminum oxide abrasives in cut-rate and durability, making it an excellent choice for moderate stock removal and surface preparation. Key Features: It comes in a variety of widths and lengths and can be used to sand both wood and metal. It has a film splice for added strength when grinding under high pressure.
